Letters Patent No. 86,055, dated .Tanna/ry 19, 1869. l l

IMPROVEMENT IN HAND-POWER LOOM The Schedule referred to in these Letters Patent and making part of the lame.

To all lwho'm, it may concern Be it known that we, GEORGE A. BROWN and J ULIA A. HUNT, of Oakalla, in the county of Iroquois, and State of Illinois, have invented a certain new and useful Improvement in Hand-Power Looms; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature v of our invention consists in the construction and general arrangement of a hand-power loom, so as to facilitate the weaving of different kinds of cloth, either plain or iigured.

In order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation, refexrin g to the annexed drawings, which form a part of this specification, and in which- Figure l is a side view, part in section;

Figure 2, a front elevation; and

Figure 3, a bottom view of the device for throwing the shuttle back and forth.

A A represent the irame, constructed of any suitable material and dimensions for locating the diderent parts of the machinery.

The lay, B, which is pivoted near tbe front end of the bottom of the'frame A, is moved by hand backwards and forwards, imparting motion to the revolv.

ing shaft, C, the journals of which have their bearings in the sides of the frame, in rear of its centre.

This motion is communicated by means of the eonnecting-rod a, which is secured to the rear side of the lay B, and to a movable collar, l), on said shaft.

To this movable collar a spring-pawl, c, is attached, which lits into notches on a stationary collar, d, on the shaft C, the whole being so arranged that, foreach motion of the lay B, the shaft G is turned one-fourth around, or it takes four backward and forward movelments of the lay to revolve the shaft once.

0n the revolving shaft C are placed four pins, c c, at equal distance from each other, which pins, as the shaft revolves, strike, one after the other, each of the four treadles fj, that are connected by cords with the four arms g g, and four short arms h h, and they, in turn, are connected with the bottoms of the four harness'- leaves k k.

The four jacks, 'i i, are located in the top of the frame A, and connected with the tops of the harness-leaves and the end of the arms l1 le..

The liarnessgleaves are bythese arms, treadles, and jacks, raised in different positions, thereby giving different sheds to the warp, and thus facilitating the weaving of dii'erent patterns.

Vhen the lay Bis moved backward, one ofthe carnhooks D catches on one ofthe eccentric-hooks, lm, bringing it to the front of the lay, where it is caught by one of the' levers E, the cam-hooks D being attached to the lower side of the front cross-beam of the frame, the hooks 'm` to the lower side of the lay, and the levers E to the front side of the same.

The lever E holds the hook m in this place until the lay again moves backward, when the other camhook D catches on the other eccentricfhook, m, bringing that to the front of the lay, to be in its turn caught by the other lever E. At the saine time the rst hook 4m is released, and iiies back to its usual place of rest, by means of coiled-wire springs n u, on the back of the lay B, ready for the next backward motion of the same.

The levers E E are formed of one straight arm, with a curved hook at one end, the straight arms crossing each other, and pivoted to the lay, as shown in fig. 2.

The curved hook of one is near the straight end of the other, so that when the hook mis caught by the said curved hook, it remains there until the straight arm on the other side is struck by the other hook m and its cam-hook D, when it of course releases the first hook m, as described.l

The hooks m m, being connected with blocks o o in the shuttle-boxes F F, at each end of the lay, throw the shuttle alternately from one shuttle-box to the other.

Near the lower end of one of the sides of the lay B, a rod, p, connects it with and communicates motion to the lever G, which is pivoted to the side of the frame, and, in its turn, moves the uprightshaft H, by means of the pawl lr and ratchet-wheel s, as shown in fig. 1.

- The upper end of the shaft H is provided with screwthreads, working in the pinion t, on the end of the horizontal shaft I, causing it to revolve, thereby taking up the cloth as fast as it is woven.

The screws u u, iu connection with their pivots and caps, being turned to the right or lett, cause the deadbeam J to be elevated or depressed, and cause the filling to be thrown either to the upper or lower side of thecloth.

In the lower part of the rear end of the frame A is placed the yarn-beam K, which is provided with journais, having their bearings in part of said frame.

At one end of the beam K is a pulley, around which a cord passes, through the side post of the frame, and secured to the lower end of the vertical lever L.

This lever rests on a projection ou the inner side of the frame., andin its upper end is provided with a thumb-screw, x, so that the upper end of said lever can be brought closer to .or further from the frame, thereby loosening or tightening the cord around the pulley on the beam K, and consequently regulating the letting oli of the yaru'of the web from said beam.

lhe yarn, in passing oli' from the beam K, passes over the dead-beam J, which latter may b'e raised or lowered, as already described.

Having thus fully described our invention,

What we claim as new', and desire to secure by Letters Patent, is

rlhe arrangement of the treadles ff, long arms g g, short arms h. h, and jacks t' i, in combination with the pins e e on the shaft G, for the purpose of raising or lowering the harness-leaves k It, thereby giving different sheds to the'web, substantially as herein set forth.

In testimony that we claim the foregoing, we have hereunto set our hands, this 27th day of June,1868.

GEORGE A. BROWN. JULIA A. HUNT.
